How Does a Distributor Cap Work

To understand how does a distributor cap work, we need to recognize the car distributor components and their functions. The distributor in a car is one of the components in the car's ignition system which plays a role in transmitting high voltage in the ignition coil to the spark plugs.

This distributor will be driven by the camshaft, so it can rotate no faster than the crankshaft. This allows the distributor shaft to provide voltage to the spark plugs in the right time and sequentially.

Car Distributor Components and Their Functions

The distributor consists of various components that will carry out various distributor functions in the car's ignition system. The various components and their functions include:

1. Distributor Cap

The distributor cap is the terminal that is connected to the secondary coil cable and the spark plug cable. The number of terminals depends on the number of spark plugs used.

The distributor cap has the function of obtaining high electric voltage through contact with the rotor. This voltage is then channeled by cable to the spark plug section. These components must be tightly closed to prevent foreign matter such as water from entering.

2. Rotors

The rotor functions to distribute high voltage electricity from the coil to each terminal of the distributor cap. This component has a conductor that is connected to the ignition coil secondary cable.

There is a free conductor at the other end of the rotor. This allows high-voltage electricity to flow to the wires as the rotor passes through the front of the distributor cap terminals.

When the distributor shaft rotates, the rotor also rotates. This round will also distribute high-voltage electricity to each spark plug.

3. Distributor Shaft

The distributor shaft or distributor shaft is in the center of the distributor and is connected to the engine camshaft. This component connects various components with their gears.

The lower part of this component is connected to an oil pump which is connected to the crankshaft, while the upper part is connected to a rotor which distributes high voltage electricity to all spark plugs.

4. Breaker Plate

Breaker plate is a place for platinum. This component is connected to the vacuum advancer and functions as a space for adjusting the platinum gap.

The breaker plate can move and can shift according to the movement of the lever on the vacuum advancer. This makes the ignition timing move back and forth according to the needs of the engine

5. Platinum

Platinum or contact point is a component that functions to disconnect the electric current from the primary coil. Called platinum because this component uses platinum.

When lit, platinum is in a connected state. When the shaft rotates, the cum lube that sticks to the distributor shaft will touch and push the platinum feet. This causes the platinum contacts to become tenuous which then breaks the electric current.

Platinum can open and close up to thousands of times per minute when the car engine is running.

6. Capacitors

Capacitor or condenser is a component that functions to absorb electrical sparks that arise due to residual electric current when platinum electricity is cut off.

Electrical sparks will be inhibited by a capacitor that is installed in parallel with the platinum. These components are available in 0.15 microfarad, 0.22 microfarad and 0.25 microfarad sizes.

Burning platinum often occurs due to mismatched capacitor sizes. Therefore, you should follow the specifications provided.

7. Advanced

Advancer is a component that functions to regulate ignition time produced by the distributor. Advancer is divided into two, namely:

8. Vacuum Advancer

This component uses vacuum air generated by the intake manifold. The breaker plate and vacuum advance sections will work according to the vacuum in the intake manifold.

9. Centrifugal Advancer

This component uses the rotational speed of the engine rpm to shift the breaker plate. The higher the engine speed, the more advanced the ignition timing.
